In the US from August 19 to September 29

My itinerary is as follows:
Portland: August 19 to 25
San Francisco: August 25 to 28
Burning Man: August 29 to September 4
Tahoe City: September 4 to 6
San Francisco/Silicon Valley: September 6 to 16
St Louis: September 17 to 21
Charleston, SC to Washington DC to New York City: September 21 to September 29

Will our paths cross? Perhaps you’ll be in a city not too far away? While I already have my plane tickets booked, I’d be more than happy to drop by your town in between my flights.

Also, if you’re in the Bay Area, DC or New York, I’m on the lookout for a comfy couch or two. Would you happen to have space for a houseguest for a few nights?
